how to take log of negative values on eviews

Postby VanessaTram » Fri Aug 18, 2017 10:32 am

Hi guys,
I am very new to Eviews, I have underwriting profit/loss values, some of them are negative. As I know in dealing with price I need to take log, but I do now know how to take log for those negative numbers ?
Also the one I am doing bases on literature review, other writers used AR(2), i do not know if i can use AR(2) model straight on my data or i have to test whether my data is suitable for AR(2) or not ??
thanks.

Negative numbers don't have logs. Nothing to do with EViews.
